Objectives and content of the SISEA project:
The aim of SISEA project is to contribute to improving the detection and the treatment of epidemic episodes in South-East Asia
The specific objectives of the SISEA project aim to:
" Establish a program for epidemiological surveillance and investigation of epidemics caused by emerging viruses
" Establish a network of laboratories and develop regional coordination in these fields in association of WHO
9
3 COMPONENTS
C1: Strenghtening the reference laboratories and establishing a network among them. Increasing the capacities of the lab. to identify pathogens, particularly viral pathogens, and qualify them
C2: Improving the epidemic alert on emerging viruses in each country - Strenghtening national epidemiological surveillance system
- Increasing the involvement of sentinel centers in the network
- Investigating epidemic episodes C3: Strenghtening the epidemic response network at national and regional levels: - In each country, strengthening the connections and coordination between various sector involved in surveillance (IO / WHO, OIE; NGOs)
- Developing relationships between the various countries (joint training, …)
- Strengthening regional coordination
- Including RIIP’Institutes in a vast network coordinated by WHO
- Technical and scientific oversight of the SISEA project activities and dissemination of the results 10

Public health and research = mutual feeding Research → Public health: cf. Previous slides
Public health → research : Publications supported by the activities of SISEA.
Limitations: data have been collected according to a surveillance objective, and no research design has been really set up regarding to scientific research questions, and financial support is provided for public health concerns
However, the observation of the data rises fundamental or applied research questions: co-infections, diagnosis tools, negative samples (more or less 50%...)

• Bacterial resistance: characterization and determinants
• Risk factors for severe infections by pathogen
• Phenotypic and genotypic determinants of viral virulence
• Viral resistance to antivirals
• Diagnosis of SARI by use of scoring system for severity
• Bacteria of interest: M. tuberculosis, B. pseudomalleii, K pneumoniae
• Viruses of interest: influenzas, HRV, RSV, hMPV, BocaV
• Clinical outcomes: guidelines/recommendations/GCP for improving patient management, both in ARI and AES

After 2010 ...?
" Needs and wishes from the partners
" Funding ? Who ("WHO"?, AFD, ADB, US-CDC, DHHS, ...)
" Network of laboratories and of hospital-based sentinel sites set up at the end of the project = sustainability of the system
" Knowledge, know-how, applicable for many lab techniques
" Geographical expansion within a country or to other countries?
" Other pathologies (rabies, …), or other EID concerns as viral/bacterial resistance as an emerging infectious disease event
" Improving connection between human and animal surveillance (in line with “One World One Health" initiative
" Integration with environmental issues and climate change under the scope of risk assessment
